Nycon® Glass Fiber Reinforced Polymer (GFRP) Composite Rebar is ideal when you need reinforcement but can’t use traditional steel rebar.
Steel used for reinforcement may cause major corrosion issues due to climate and exposure to chlorides and have resulted in severe deterioration. Governments and building owners who are facing an estimated $74B of ongoing repairs and potentially dangerous failures have now included Composite Rebar (GFRP) in their corrosion protection policies. Nycon® GFRP Composite Rebar reinforcement has answered the call in providing an economical, safe and long-term sustainable solution with initial and long-term cost savings.
All Composite Rebar is not created equal. In offering the widest range and highest grade of GFRP (glass fiber reinforced polymer) Nycon® is able to provide the best performance at the best cost. The mechanical and physical properties of FRP reinforcement are critical in determining performance and long-term durability. Nycon® GFRP Composite Rebar is the only bar available in the market that meets all three grades (40GPa, 50GPa & 60GPa) as per the CSA S-807; offering the highest grade in the market up to GUTS of 1372 MPa and 65GPa down to its LM line of 800MPa and 44GPa bar. This allows optimization of design and best cost vs performance ratio – FLEXIBILITY.
Why Composite Rebar?
• Non corrosive, never rusts
• Lower cost than epoxy or stainless rebar
• 25% the weight of steel, easy placement
• 1.5x – 2x higher tensile strength than steel
• Coverage requirements as low as 3/4”
• Excellent fatigue resistance
When to use it?
• Ultra thin concrete elements
• Corrosive / acidic environments
• Magnetically sensitive projects
• Where electrical corrosion exists
• Cannot be bent in the field or with heat
• *Design methodology different than carbon steel
